Manald Heal (Diablo III)

As of patch 2.4.3, it gained a unique affix: any enemy stunned with Paralysis will also take a huge Lightning damage blow, regardless of the attack's Proc Coefficient, as long as Stun actually occurs. Channeled skills have a reduced chance to trigger it.

Originally the bonus was intended to work differently:

Lightning damage done by your Arcane Power spender skills does an additional 20-25% of the damage over 5 seconds. This damage-over-time effect can be refreshed by additional Lightning damage and stacks.

Prior to 2.4.3, it was one of the two rings, the other being Stone of Jordan, and one of the few non-class-specific items capable of increasing the maximum resources of any class.
